The beauty of a Registry is to show how many are registered, I don’t think we want duplicate VINs. In autokunst’s case, I probably created the original Seen in Ad entry. When an owner shows up, I reset the password so they could edit the entry.
I talked to Dan about this. You can have duplicate entries if desired. For the counts section, you need to count distinct VIN’s instead of records. With that said duplicates may be confusing.
